| Popis: | In order to model configurations driven by broadband sources (e.g. digital signals), it is desirable to employ a full-wave modeling technique that works well at both high and low frequencies. This paper describes a method for improving the low-frequency performance of existing full-wave boundary element techniques and demonstrates how this method can be used to calculate static electric fields and charge distributions. The new approach involves performing a linear transformation on the moment matrix utilizing an LU decomposition and matrix reconstruction. It does not require special basis functions and is relatively easy to implement in existing boundary element codes. Examples presented demonstrate how modified full-wave software accurately calculates static field and charge distributions for a variety of configurations using the same algorithms and the same input used to do high-frequency calculations |
